| Abstract: | In this paper, a line-spring model for the general beam with an edge crack and its theoretical explannation is presented. The fracture analysis of the cracked beam can be simplified as a one dimensional problem by using this model.Numerical results of static and dynamic fracture of three-point bending beam with an edge crack are given in the end, which show that the model is of high precision. |
